Google Inc. last week introduced a revamped release of its Google Analytics service with several updates, including an expansion of the website usage monitoring tool’s data reporting capabilities. Products like Google Analytics continue to attract the attention of large companies looking to understand how users arrive at their Web sites — and what they do once they get there. Data compiled by such products can help webmasters make their sites more effective tools for displaying online ads, providing sales leads and generating e-commerce transactions, Google said. American Cancer Society Inc., a Google Analytics user for about 18 months, has been testing the new version of the service for the past month and found significant improvements, said Adam Pellegrini, the Atlanta-based nonprofit’s online strategy director. In particular, he said, the ability to schedule the automatic creation and e-mail delivery of reports as PDFs has been a big help for the group’s two Google Analytics users. The product previously required that those users manually reformat reports into PDF files and send them out via e-mail, he said. Pellegrini would like Google to add the ability to deliver analytics reports and notifications via RSS content syndication, as well as to create rich desktop applications that would allow the service to be used offline. Urchin acquired Google entered the web analysis market a little over two years ago with its acquisition of San Diego-based Urchin Software Corp., whose technology forms the basis of the service. Brett Crosby, a Google Analytics senior manager, said that the upgrade is designed to make the product’s interface more intuitive and its data clearer and easier to digest. Thus, the service can be more effective in providing data needed to make business decisions, Crosby said. The user interface has been redesigned, and the product has gained new ways of presenting Web usage information and displaying and delivering reports, he added. Google has also added what it calls “plain language” descriptions of the data to make it more understandable, Crosby said. Google will begin rolling out the Analytics upgrade today, and it expects to finish it in a few weeks, Crosby said.
